The lower face of the sheet body is equipped with lower convex platform, and first is equipped on the outer surface of the convex platform and the interior survey surface of lower convex platform
Waterproof layer is equipped with the second waterproof layer on the front and rear end of the sheet body in the periphery of buttcover plate.
On the basis of above-mentioned technical proposal, the sheet body using high-strength water-tight concrete make, the convex platform, under it is convex
Platform, piece ridge and piece body by integral forming.
On the basis of above-mentioned technical proposal, first waterproof layer and the second waterproof layer are all made of rubber making.
On the basis of above-mentioned technical proposal, the end face of described ridge and the surface of buttcover plate in the same plane, described
Two waterproof layers slightly protrude from plane where the end face of piece ridge and the surface of buttcover plate.
On the basis of above-mentioned technical proposal, the circular arc of the sheet body is 1/8 circle, is connected by arch screw bolt between two sheet bodies
Connect fixation.
Compared with prior art, the utility model has the following advantages：The inner surface of the utility model is equipped with piece ridge,
Have better support force, structural stability more preferable under the weight concrete of identical weight；It is equipped at four connection sides anti-
Water layer, water resistance are more preferable；It is installed using upper lower convex platform crimping mode, installation is simple, improves construction efficiency, and overall structure is more steady
Fixed, resistance to stress effect is more preferable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
